                    id: 'cvs',
                    data: data,
                    options: {
                        grouping: 'stacked',

            /**
            * Make the AJAX call that fetches the CSV data
            */
            RGraph.AJAX('/sample.csv', callback);
        })
    </script>
    
    <p>
        This basic example uses AJAX to request a CSV file from the server and then parses it with Javascript to convert it into usable
        data. You can see the CSV file <a href="http://www.rgraph.net/sample.csv">here</a>.

        <b>Note:</b>
        In October 2013 a new CSV reader was added to RGraph. It makes reading CSV files much easier. You can read about
        <a href="http://www.rgraph.net/docs/csv-file-reader.html">the new CSV reader</a> here.
